Once a king went out of the city in disguise, He wanted to know about his own reputation in public. He saw a man was sitting under the tree. The king asked him, " What about your king, Is he a good person." He replied," No! our king is very cruel person and persecute the innocent people without any fault or mistake." The kind said," Do you recognize me." That man said no. The king said that I was the king of the country. To hearing this that man got so much nervous or upset. But that man was very clever and replied."Sir, do you know me. I am the son of such and such merchant and there are three days in every month when I take leave of my sense. And today is the day out of these three days." The king smiled and forgive him.
